Installing Artist 7 in Yosemite

Hi Guys , can someone help me please . I have just installed Cubase Artist 7 on my i mac , it says it is installed but I cant find it anywhere . I tried the Installer tool but it’s still the same . Is there an update for this version os yosemite ? I should add that i managed to install studio 4 without a problem .

Try this tool:

Thanks bud , I already tried that but it still didnt work . I find it strange that an older version i.e. Studio 4 loads without any issues , but the newer version doesn’t install . It goes through the install process and ends saying that it is installed , but i cant find it .
